Patented Dec. 1, 1931 UNITED STATES HANS P. SORENSEN, OF PORT CHESTER,NEW YORK SAFETY MEANS FOR GAS APPARATUS Application filed January 22,1930. Serial No. 422,651.

This invention relates to new and useful improvements in safety meansfor gas apparatus, gas stoves, and the like; and it has been an objectof this invention to provide a device, which, when applied and properlyconnected to a gas apparatus, will automatically light the gas, when thelatter is turned on, thereby guarding against the waste of gas, anddeplorable accidents occurring, when people, and especially children,through mistake or inadvertence happen to open the gas jets by turningthe gas-cocks, or when they open for the gas but forget to apply thepilot.

This device, while embodying the principles of my invention in a generalmanner, as illustrated herein, may, however, be subject to minormodifications.

As the construction of the device is comparatively simple the cost ofmanufacturing should be proportionately low; thereby assuring, it isthought, a great market for this invention.

it-h the above and other objects in view, this invention consists of thenovel features of construction, combination and arrangements of parts,hereinafter fully described, claimed and illustrated in the accompanyingdrawings forming parts of this specification, and in which similarcharacters of reference indicate corresponding parts in all views, and

in which:

Figure 1 is a top plan view, showing part of a gas stove with my deviceattached; Figure 2 is a front elevational View of same, while Figures 3,4 and 5 are detail views closely illustrating the difierent parts of mydevice.

Referring more particularly to the drawings, indicates a gas apparatus,which is connected to a feeding gas pipe 11 by means of the tubes 12;the flow of gas being as usually controlled by the gas-cocks 13, while afollows: I

pilot button 14; serves to light said gas.

To the said gas pipe 11 is attached in a i pivotal manner a member, orflat oblong bar,

15'; the said bar being connected by means of hinges 16 to clamps 17,which in turn engage the said pipe 11. A

'On top of the said bar are arranged a number of raised portions,,orparts, 18, the said portions having one side, or surface, formed as anacclivity 19, and the opposite side, or surface, as a declivity 20; theportions 18 may be attached to the said bar in any suitable manner, ormay be formed integral there with. V The device or part of it may bemade of all metal or of any suitable material.

Below the said bar is loosely. arranged a coiled spring 21 made toconvey any pressure exerted upon the said bar to the pilot; the saidspring may be wound around the pilot, and project above the latter, orit maybe formed integrally with a metal plate suitable to be fastened tothe pilot in Figure 5.

A transversely positioned member 22, terminating. atone end inbifurcated sections 23, is turnably attached to the neck of a gascock,the said member having the inner surfaces of the said bifurcatedsections shaped to fit the said neck, and is ustably attached to thelatter by means of a screw and wing-nut button, as shown "arrangement24. However,the shape of the said member, and the manner of attachingand regulatingit may well be varied."

The member 22 is atthe' end opposite the said bifurcated sections formedwith an angular downwardly projecting sectionj25; a pointer, 26 ispivotally connected to the lower end 'of the section 25 in such a mannerthat the said pointer will collapse or fold in one ,direction'only. Aspring 27 is connecting the section 25 to the pointer 26 inorder to urgethe two parts into alignment, as shown in Fi'gures'2and 3.

The operation of the device is briefly as Upon turning the gas-cock inorder to open for the gas, the pointer 26-0f the member-'22 willsimultaneously ascend the acclivity 19, and thereby exert a pressureupon the bar 15, which pressure by way of the spring 21 will be relayedto the pilot-button, causing the pilot to operate and light the gas.When the gas-cock with the member 22 has traveled a certain distance, ofan imaginary circle, the pointer 26 of the member 22 will descend thedeclivity 20, thereby relieving the pressure upon the bar 15 andconsequently discontinue the operation of the pilot.

In closing the gas by a turning movement in the opposite direction thepointer 26 will automatically and gradually collapse upon striking thesloping surface of the declivity 20, as shown in Figure 4, therebypermitting the member 22 and the gas-cock to travel back to the originalor closed position without ex pressure upon the bar or actuatingv ertingany the pilot.

It is obvious that changes may be made in the form, construction andarrangement of the several parts, as shown, within the scope of theappended claims, without de arting the spirit of the invention, and donot therefore desire to limit myself to the con- .struction andarrangement shown and described herein.

- What I claim as new, and desire to secure by Letters Patent of theUnited States, is:

1. A device of the class described, comprising an oblong bar, means forpivotally engaging said bar to a gas pipe, a plurality of elevationsarranged upon the top of said bar, the said elevations being formed withone surface gradually ascending'and the other surface steeplydescending, means for establishing contact between said bar and a.pilot, a plurality of pressure-exerting members adjustably attached to acorresponding number of gas-cocks for the purpose of actuating said barby means of the said elevations, the said members each comprising abifurcated neckportion for connection with a as-cock, a downwardlyextending portion ormed upon one side of said neckportion and integraltherewith, a hinged portion connected to said downwardly extendingportion and adapted to fold in one direction only, substantially as andfor the purpose set forth.

' 2, A- device of the class described, comprisportion formed upon oneside of said neckportion and integral therewith, a hinged portionconnected to said downwardly extending portion and adapted to fold inone direction only, and a spring for keeping said hinged portionnormally in elongation of the said downwardly extending neckportion,substantially as and for the purpose set forth.
